rotatable in an outer casing. Inaddition, the

outer casing is provided with relatively compli-. cated means forpreheating air and for introduc ing said air into the rotatablecylinder, Suction hoods and conduits are also provided to remove themoisture laden air from the perforations in the periphery of thecylinder as the latter rotates. This'type of construction utilizes asubstantial amount of material and is expensive to manufacture andassemble. Furthermore, the heated air tends to travel to the peripheryof the cylinder before it has extracted a maximum amount of moisturefrom the garments. As a result the drying operation is renderedrelatively slow and inefiicient.

It is a general object of the present invention to provide a tumblerwherein a novel and simple arrangement is utilized for causing efiectivecirculation'of heated air through the cylinder while the latter rotates,the heated air being so directed as to cause it to emciently act uponthe garments within the cylinder to extract the maximum amount ofmoisture therefrom.

A further object of the invention is to provide a cylindrical tumblerhaving a solid, unperiorated peripheral wall, having a garment receivingopening at one end of the cylinder, heating means at the same end, andan air exhausting means at the opposite end from the heating means,there being novel means for conducting heated air into the .drum and forcausing said air to circulate efiectively in the drum while the latterrotates.

A further object of the invention is to provide a construction as abovedescribed wherein there is an exhaust conduit positioned axially of thedrum at one end thereof, and wherein the fixed heating means surroundsthe garment receiving opening and surrounds a perforated annular flangewhich projects from the marginal edge of the garment receiving opening,said annular flange being rotatable with the drum.

A further object of the invention is to provide a construction as abovedescribed wherein the drum is rotatable in an outer casing, and whereinthere is a fixed door in the front of the outer casing which is inregistration with the garment receiving opening in the front end of thedrum, the perforated annular flange surrounding the garment receivingopening of the drum having its projecting edge rotatable closelyadjacent to the periphery of the fixed door, and the heating means beingpositioned to surround said annular flange and being accommodated in thespace between the front of the casing and the front of the drum,

Other objects of the invention are to provide a tumbler which is simpleand inexpensive to man ufacture, easy to assemble, and which is welladapted for the purpose described.

With the above and other objects in view the invention consists of theimproved tumbler and all its parts and combinations as set forth in theclaims and all equivalents thereof.

In the accompanying drawing illustrating one complete embodiment of thepreferred form of the invention, in which the same reference numoralsdesignate the same in all of the views:

Fig. l. is a vertical sectional view taken axially through the cylinderapproximately on the line l--l 011F352; and

Fig. 2 is a. front view of the improved tumbler, part being broken away.

Referring more particularly to the drawing, the numeral ti designates asuitable supporting frame having legs Suitably supported on the base arerollers it, two on each side, which are engageable in external tracks iton the periphery oi a rotatable drum E2. The rollers not only serve todrive the rotatable drum but also support the same in its rotatingmovement. The rollers may be driven by any suitable means. In the illustrated form of the invention there is a pulley it which is driven froman outside source and said pulley causes rotation of a shaft M for oneset of the rollers ill. Motion may be transmitted by means of an endlesschain. or by any other suitable means from the shaft id to the shaft 55for the other set of rollers ill. Thus rotation of the driven pulley itin a desired direction causes simultaneous rotation of the two sets ofdrum supporting rollers ill and rotation of the drum 62. Any othersuitable means may be utilized for driving and transmitting power to therollers. Furthermore, the rollers may be used merely as a rotatablesupport and the drum may be driven through any type of transmissiondesired.

The tumbler cylinder or drum :12 has an unperforated. peripheral wall.it and has a front wall ll formed with a garment receiving opening id.Surrounding the garment receiving opening ill is an outwardly projectingannular flange it. The flange it extends at an angle of approximately 45and is formed with perforations 2&3.

3. A tumbler comprising a rotatable cylinder having a garment receivingopening in its front end and having an air'outlet opening in its rearend, a fixed outer casing housing at least said front end of thecylinder and having an air admission opening, said casing having a frontportion spaced from the front of the cylinder and provided with agarment receiving opening in alinement with the garment receivingopening of the cylinder, a door for closing said openin of the outercasing, an apertured annular flange surrounding the garment'receivingopening of the rotatable cylinder and rotatable with the cylinder andprojecting into the front space be tween the casing and front end of thecylinder, the front edge of said annular flange being closely adjacentto the periphery of the door opening of the casing, heating meanspositioned in said front space and surrounding said flange, and meansincluding a fan for drawing air into the casing and for causing movementof said air radially along the exterior of the front end of .thecylinder in said front space, past said heating means, through theapertures in said annular flange and longitudinally through the cylinderto said air outlet opening.

4. Atumbler comprising a rotatable cylinder having a garment receivingopening in its front end, a fixed outer casing housing at least saidfront end of the cylinder and having an air admission openihg, saidcasing having a front portion spaced from the front of the cylinder andprovided with a garment receiving opening in alinement with the garmentreceiving opening of the cylinder, a door for closing said opening ofthe outer casing, an apertured annular flange the casing and front endof the cylinder, the front edge .of said annular flange being closelyadjacent to the periphery of the door opening of the casing, heatingmeans positioned in said front space and surrounding said flange, andmeans including a fan for drawing air into the casing and for causingmovement of said air radially along the exterior of the front end of thecylinder in said front space, past said heating means, through theapertures in the annular flange, and longitudinally through thecylinder.

5. A tumbler comprising a rotatable cylinder having a garment receivingopening in its front end, a fixed outer casing housing said front endconical in shape surrounding the garment resurrounding the garmentreceiving opening of the rotatable cylinder and rotatable with thecylinder and projecting into the front space between ceiving opening ofthe rotatable cylinder and rotatable with'the cylinder and projectinginto the front space between the casing and front end of the cylinder,the front edge of said annular flange being closely adjacent to theperiphery of the door opening of the casing. heating means positioned insaid front space and surrounding said flange, and means including a fanfor drawing air into the casing and for causing of movement of said airradially along the exterior of the front end of the cylinder in saidfront space, past said heating means, through the apertures in theannular flange, and longitudinally through the cylinder.
